The current slabs
Residential consumers receive ₹30,000 per kW for the first two kilowatts and ₹18,000 for the third under the central scheme, capped at ₹78,000, with the Tamil Nadu state subsidy paid additionally on top. Group housing societies receive a separate central rate for common-area systems.
Who qualifies
You need a residential service connection in the applicant's name, a roof you own or have written permission to use, and installation by a registered vendor using ALMM-listed modules and BIS-certified inverters. Commercial connections are not eligible.
Documents to keep ready
For subsidy and a solar loan, keep your bank passbook, PAN card, Aadhaar card, passport-size photo, latest EB bill or EB card and roof ownership proof or owner consent ready. For an EB additional-load application, keep your latest property tax receipt, passport-size photo and EB card ready. Your bank or EB office may ask for more documents.
How long it actually takes
Registration and approval typically take one to three weeks, installation a few days, and inspection plus meter change another two to four weeks. Subsidy usually credits within 30 to 45 days of the net meter being installed.
